Summary
Grafana OSS and Grafana Enterprise have a missing authorization check that lets any logged-in user, including Viewers and service accounts with no permissions, create, externally publish, and delete dashboard snapshots. An attacker can reach this remotely over the network with a low-privilege login, and no user action is needed.
